Blender armature imported as FBX to UE4 doesn't keep bone offset
You can create a new root bone, which will be parent af all others rig's bones, and set it on the floor, so that UE will not have to move anything. Similarly you can replace every &quot;keep offset&quot; option with a new bone, so that all the bones chains will not be &quot;interrupted&quot;. UE requires a general root bone that will be placed at loc (0,0,0). Every bone is requested to be weighted to one mesh vertex at least. If some vertices are not weighted to any bone, they will be automatically fully assigned to the root bone.
